It might help if you described the application. I am guessing that you have a small number of values (5? 10? 15?) and that using direct indexing with a ListedColormap will be the simplest way to get what you want. I have recently made this easier in svn, as illustrated by the second panel in examples/colorbar_only.py, but this is not yet available in a released version of mpl. A simpler use of a ListedColormap is given in examples/contourf_demo.py, in the last plot; this is the same in recent mpl releases as in svn. > > I read the cookbook entry on "Doing your own colormap", but can't seem to > bring my mind into it!
